In some embodiments, the mounting seat 42 can improve stability of the light-emitting unit 21 when the light-emitting unit 21 and the lamp holder 1 are locked by the connection unit 41 and facilitate adjustment of the light-emitting direction of the light-emitting unit 21.

In some embodiments, in order to connect the light-emitting unit 21 and the connection plate 4111 through the rotation axis 43, one end of the rotation axis 43 may be connected with a connection seat 44, and the connection seat 44 may be connected to the light emitting unit 21 by a fastener. The other end of the rotation axis 43 may be provided with a threaded hole 431, and the connection plate 4111 may be provided with a penetrating hole 4114. The rotation axis 43 may be connected to the connection plate 4111 by a screw bolt passing through the penetrating hole 4114 and threadedly connected to the threaded hole 431. In order to prevent the rotation axis 43 from rotating relative to the connection plate 4111, one of the connection plate 4111 and the rotation axis 43 may be provided with a positioning hole 4113, the other may be provided with a positioning protrusion 432, and the positioning hole 4113 and the positioning protrusion 432 may be inserted. For example, the positioning hole 4113 may be disposed on the connection plate 4111, and the positioning protrusion 432 may be disposed on an axial end surface of the rotation axis 43. There may be two positioning protrusions 432. The two positioning protrusions 432 and the threaded hole 431 may be arranged in a same direction, and the threaded hole 431 may be located between the two positioning protrusions 432. In order to simplify processing of the positioning hole 4113 and the penetrating hole 4114, radial side walls of the positioning hole 4113 and the penetrating hole 4114 may be drilled to form an oval hole.

In some embodiments, the second connection part 412 may be a protruding structure. The protruding structure may be inserted into any locking hole 4112. The connection plate 4111 may be elastically deformed, so that the first connection part 411 may be separated from the second connection part 412.

The protruding structure may be a protruding part of the second connection part 412, or may be a connection functional member disposed on the second connection part 412. For example, the protruding structure may be a tenon-and-mortise structure or a screw bolt structure. The first connecting portion 411 and the second connection part 412 may be connected and separated through a structure corresponding to the protruding structure disposed on the connection plate of the first connection portion 411 and a certain deformation.

In some embodiments, when the light-emitting direction of any light-emitting unit 21 needs to be adjusted, it may be only necessary to apply an external force to the connection plate 4111 in an opposite direction when the protruding structure is inserted into the locking hole 4112, and the connection plate 4111 may be elastically deformed, so that the protruding structure may gradually withdraw from the locking hole 4112. After the protruding structure withdraws from the locking hole 4112, the light-emitting unit 21 may be rotated, and the external force applied to the connection plate 4111 may be removed to restore the connection plate 4111 to a natural state after the protruding structure is aligned with an appropriate locking hole 4112. During the process, the protruding structure may be gradually inserted into the locking hole 4112, and the structure is simple and the operation is convenient.

In some embodiments, after the protruding structure is disengaged from the locking hole 4112, the light-emitting unit 21 may be supported by the mounting seat 42 at two ends of the light-emitting unit 21 to prevent the light-emitting unit 21 from being separated from the lamp holder 1, and at the same time, it may be convenient to rotate the light-emitting unit 21 to align the protruding structure with the appropriate locking hole 4112. After the protruding structure is inserted into the locking hole 4112, when the light-emitting unit 21 and the lamp holder 1 may be locked by the insertion of the protruding structure and locking hole 4112, the light-emitting unit 21 may be supported by the mounting seat 42, which may reduce a requirement on connection strength when the protruding structure and the locking hole 4112 are inserted.

In some embodiments, the second connection part 412 may also include a limit part. The limit part may abut against the connection plate 4111 when the protruding structure is inserted into any locking hole 4112. In some embodiments, the protruding structure may be configured to insert any locking hole 4112 and connect to the lamp holder 1.

In some embodiments, the insertion of the protruding structure and the locking hole 4112 may be limited by the limit part, which may prevent an insertion depth from being too large, and make it difficult for the protruding structure to disengage from the locking hole 4112. The structure is simple and easy to process. In order to facilitate the insertion of the protruding structure and the locking hole 4112, an outer surface of the protruding structure may be a cambered surface. When the protruding structure is inserted into the locking hole 4112, the outer surface of the protruding structure may have a function of guiding the connection plate 4111, so that the protruding structure may be inserted into the locking hole 4112 more easily.

In some embodiments, the protruding structure may be a step structure. In a specific embodiment, the protruding structure may include a small diameter section that can be inserted into any locking hole 4112 and a large diameter section that connects the small diameter section to the lamp holder 1. A step surface formed by the small diameter section and the large diameter section may be the limit part. It should be noted that the limit part is not limited to the step surface of the above-mentioned step structure. The limit part may also be directly mounted on the lamp holder 1.

In some embodiments, the dynamic connection component 4 may include the connection unit 41. The connection unit 41 may include a first connection hole, a second connection hole, and a locking member. In some embodiments, the first connection hole may be disposed on one of the light-emitting unit and the lamp holder. The second connection hole may be disposed on the other of the light-emitting unit 21 and the lamp holder 1. The second connection hole may be an arc-shaped hole, and may be coaxial with a rotation axis of the light-emitting unit 21 relative to the lamp holder 1. The locking member may be penetrated through the first connection hole and the second connection hole. The locking member may move in the second connection hole along a circumferential direction of the rotation axis, and may lock the light-emitting unit 21 and the lamp holder 1. Merely by way of example, the first connection hole may be disposed on the lamp holder 1. The second connection hole may be disposed on the connection plate 4111. The locking member may be a screw bolt and a screw nut. The screw bolt may pass through the first connection hole and the second connection hole and connect to the screw nut. After the light-emitting unit 21 is rotated to a suitable position, the screw nut may be tightened, and a head of the screw bolt may abut against the connection plate 4111, that is, the light-emitting unit 21 may be locked with the lamp holder 1.

It should be noted that the being coaxial is not being 100% coaxial. However, considering a reason of processing error, it is only required that when the light-emitting unit 21 is rotated, the connection plate 4111 may be rotated under transmission of the rotation axis 43 and may be inserted into any second connection hole.

The first connection hole may be a hole disposed on the light-emitting unit 21 and the lamp holder 1. The light-emitting unit 21 and the lamp holder 1 may be locked when the light-emitting unit 21 is rotated to a suitable position through the locking member and the second connection hole. A specific structure of the first connection hole is not limited, which may be an arc-shaped hole or a rectangular hole. For example, the first connection hole may be disposed on the lamp holder 1. The second connection hole may be disposed on the connection plate 4111. The locking member may connect the first connection hole with the second connection hole. After the light emitting unit 21 is rotated to a suitable position, the locking member may be locked, and the light-emitting unit 21 may be locked with the lamp holder 1.

The second connection hole may be disposed on the other of the light-emitting unit 21 and the lamp holder 1. The second connection hole may be coaxial with the rotation axis 43 of the light-emitting unit 21 relative to the lamp holder 1. The second connection hole may be an arc-shaped hole.

The locking member may be a member that penetrates the first connection hole and the second connection hole, move in the second connection hole along the circumferential direction of the rotation axis 43, and lock the light-emitting unit 21 and the lamp holder 1. A specific structure of the locking member is not limited, which may be a screw bolt and a screw nut, or a rivet. For example, the locking member may be a screw bolt and a screw nut. The screw bolt may pass through the first connection hole and the second connection hole and connect to the screw nut. After the light-emitting unit 21 is rotated to a suitable position, the screw nut may be tightened, and a head of the screw bolt may abut against the connection plate 4111, that is, the light-emitting unit 21 may be locked with the lamp holder 1.

FIG. 13 is a sectional view 2 illustrating a plant lamp (mounted with a heat dissipation unit) according to some embodiments of the present disclosure. FIG. 14 is a partial enlargement schematic view illustrating a part B in FIG. 2 according to some embodiments of the present disclosure. In some embodiments, the plant lamp may also include suspension parts 6. Two opposite ends of the lamp holder 1 may be respectively provided with suspension parts 6, each of which is configured to hook and connects with a hook for the plant lamp.

In some embodiments, as shown in FIGS. 13 and 14 , two suspension parts 6 may respectively be connected to the two opposite ends of the lamp holder 1, and plant lamp may be suspended and mounted by connecting the suspension parts 6 with the hooks for the plant lamp. For example, the two suspension parts 6 may be disposed on the two opposite ends of lamp holder 1 in the second direction.

In some embodiments, each of the two ends of the suspension part 6 may be respectively connected with a mounting ring 61. An upper side of the lamp holder 1 may be folded inward to form a flange 112. The mounting ring 61 and the flange 112 may be connected by a fastener.

In some embodiments, the upper side of a first frame 11 may be provided with the flange 112 folded inwardly. The mounting ring 61 and the flange 112 may be connected by a fastener. Specifically, the fastener may be a connection screw bolt 71 and a locking screw nut 72. A free end of the connection screw bolt 71 may pass through the mounting ring 61 and the flange 112 in sequence and then may be connected to the locking screw nut 72 for locking, and a head of the connection screw bolt 71 may prevent the mounting ring 61 from disengaging from the head of the connection screw bolt 71, so that mounting between the suspension part 6 and the first frame 11 may be realized.

In some embodiments, in order to facilitate mounting the suspension part 6 on the hook for the plant lamp, the suspension part 6 may rotate relative to the lamp holder 1. In a specific embodiment, an elastic element 73 may be sandwiched between the head of the connection screw bolt 71 and the mounting ring 61, such as an elastic washer or a spring that is sleeved outside the connection screw bolt 71. An inner diameter of the mounting ring 61 may be larger than a diameter of the connection screw bolt 71, so that the suspension part 6 may rotate at a small angle relative to the connection screw bolt 71 when the plant lamp is mounted. At the same time, in order to improve stability of the plant lamp in a suspension mounting, the elastic element 73 may be applied to exert an external force on the mounting ring 61 to press the mounting ring 61 to the flange 112.

In some embodiments, at least two light-emitting units 21 may change together. Changing together (or linkage) refers to a plurality of light-emitting units 21 making a preset position change at the same time. The position change may be set in advance. The position change may be the same or different. For example, the plurality of light-emitting units 21 may be changed to a same light-emitting direction together. As another example, the plurality of light-emitting units 21 may be deflected in different directions at the same time. Merely by way of example, for a plant that likes light, the plurality of light-emitting units 21 may be deflected to the plant at 6:00 pm to supplement light for the plant. In some embodiments, a count of the light-emitting units 21 changing together may be set according to light intensity requirements of different regions, different plants or different growth stages of a same plant. For example, the stronger the light intensity required for a plant, the greater a count of the light-emitting units 21 changing together chosen. Merely by way of example, for a plant that likes light, 10 light-emitting units 21 may be set around the plant for linkage, and deflected to the plant together at 6:00 pm to supplement light for the plant. For a plant that does not like light, but still needs supplementary light, 3 light-emitting units 21 may be set around the plant for linkage, and deflected to the plant together at 6:00 μm.

FIG. 16 is a schematic diagram illustrating a plurality of light-emitting units changing together according to some embodiments of the present disclosure.

In some embodiments, different light-emitting angles may be formed when the plurality of light-emitting units are linked to change together. In some embodiments, a specific count of the light-emitting units 21 is not limited herein. For example, as shown in FIG. 16 , the light-emitting units 21 of the plant lamp may be set to four according to actual conditions, so as to illuminate different plants at different growth stages at the same time. At this time, three of the four light-emitting units 21 may be linked to form different angles, so as to satisfy light requirements of two plants respectively. For example, a large plant may require more light. Three light-emitting units in FIG. 16 (the top three light-emitting units in the figure) may be linked, which may be set to focus on the larger plant. The other light-emitting unit (the one at the bottom in the figure) may illuminate a smaller plant to meet light requirements of different growth stages of a same plant at the same time. In some embodiments, according to different light intensities required by different plants, different light intensities required by different parts of a same plant, or a plurality of plants needing light at the same time, a plurality of light-emitting units 21 may be set to form different light-emitting angles when they are linked together.

In some embodiments, the plant lamp may also include a control rod configured to control the light-emitting units 21 to be linked to change together. In some embodiments, the plurality of light-emitting units 21 may be connected to the control rod. The plurality of light-emitting units 21 may be controlled individually or simultaneously by controlling the control rod, so as to achieve control of the light-emitting units 21 for changing together.

FIG. 17 is a schematic diagram illustrating a control rod controlling linkage according to some embodiments of the present disclosure.

In some embodiments, the control rod may be connected with the light-emitting units 21, so as to perform linkage regulation on the plurality of light-emitting units 21. Merely by way of example, as shown in FIG. 17 , three light-emitting units 21 may be respectively connected to three rods, namely a first rod 81, a second rod 82 and a third rod 83. Other ends of the first rod 81, the second rod 82 and the third rod 83 may be rotatably mounted. For example, the other end of the first rod 81 may be mounted on the lamp holder 1 through a first universal ball joint 811. The other end of the second rod 82 may be mounted on the lamp holder 1 through a second universal ball joint 821. The other end of the third rod 83 may be mounted on the lamp holder 1 through a third universal ball joint 831. The first rod 81, the second rod 82 and the third rod 83 may be all connected to the connection rod 84. The connection rod 84 may be connected to the control rods. The connection rod 84 may be controlled to perform circular or elliptical circular motion on a horizontal plane by controlling the control rods manually or mechanically, so that the three light-emitting units 21 may perform gyroscopic motion with the first universal ball joint 811, the second universal ball joint 821 and the third universal ball joint 831 as fulcrums respectively, and light-emitting directions, positions, etc. of the three light-emitting units 21 may be changed together, and linkage adjustment may be realized. In some embodiments, the connection rod 84 may be a straight rod, so as to connect a plurality of light-emitting units 21 on a same straight line. The connection rod 84 may also be a curved rod as shown in FIG. 17 , so as to connect a plurality of light-emitting units 21 not on the same straight line.

In some embodiments, the first rod 81, the second rod 82 and the third rod 83 may be set with different lengths and different initial angles relative to the horizontal plane as required, so that the plurality of light-emitting units 21 may be rotated at different angles during the linkage adjustment and finally form different light-emitting angles. In some embodiments, the light-emitting units 21 and the rods may be set to be movably connected as required, so that the light-emitting units 21 can further change the light-emitting direction when performing linkage adjustment. For example, since the light-emitting units 21 may be movably connected to the rods, under an action of gravity, after positions of the light-emitting units 21 are changed, the light-emitting units 21 may still maintain a horizontal state.

In some embodiments, the lamp holder 1 of the plant lamp may be rotated in the horizontal plane. The light-emitting direction of the light-emitting unit 21 may be further adjusted based on rotation of the lamp holder 1 itself. For example, in some cases, a light angle formed by the light-emitting unit 21 still may not meet a light requirement of a plant well. At this time, an entire plant lamp device may be further adjusted by rotating the lamp holder 1, so that the light-emitting direction of the light-emitting unit 21 may better meet the requirement.

In some embodiments, a first space may exist between the at least one heat dissipation unit 22 and the lamp holder 1. The first space may be configured to form a first heat dissipation channel 31.

The first space may refer to a gap between the heat dissipation unit 22 and the lamp holder 1.

The first heat dissipation channel may be a channel configured to discharge hot gas and including the first space. According to a structure and arrangement of the heat dissipation unit 22 and the lamp holder 1, the first heat dissipation channel 31 may have a plurality of forms, for example, may be straight or curved, regular or irregular, and the form is not limited.

In some embodiments, the first heat dissipation channel 31 may include the first space, or may also include the first space and other spaces. For example, the first heat dissipation channel may be composed of the first space and a space between the heat dissipation unit and other components such as the light-emitting unit, etc.

FIG. 18 is a schematic diagram illustrating a structure of a first heat dissipation channel according to some embodiments of the present disclosure.

In some embodiments, the first heat dissipation channel 31 may be disposed between the light-emitting unit 21 and the lamp holder 1. The light-emitting unit 21 may be disposed corresponding to the heat dissipation unit 22. In some embodiments, the first heat dissipation channel 31 may penetrate from a light-emitting side to a non-light-emitting side of the light-emitting unit 21 to enhance heat dissipation intensities of the first heat dissipation channel 31 to the light-emitting side and the non-light-emitting side of the light-emitting unit 21. As shown in FIG. 18 , space between the light-emitting unit 21 and the lamp holder may be considered as the first heat dissipation channel 31. The space may be not limited to the non-light-emitting side of the light-emitting unit 21 (side b in FIG. 18 ), but may penetrate from the light-emitting side (side a in FIG. 18 ) to the non-light-emitting side (side b in FIG. 17 ). The entire penetrating space can effectively enhance heat dissipation as the first heat dissipation channel 31.

As shown in FIG. 11 and FIG. 12 , in some embodiments, the lamp holder 1 of the plant lamp may include two first frames 11 spaced apart in a first direction L1 and disposed opposite to each other and two second frames 12 spaced apart in a second direction L2 and disposed opposite to each other. Two ends of each first frame 11 in the second direction L2 may be respectively connected to the two second frames 12. The first direction L1 and the second direction L2 may be disposed to cross each other. Two ends of each light-emitting unit 21 in the second direction L2 may be respectively connected to the two second frames 12. Each light-emitting unit 21 may be located between the two first frames 11. Each first heat dissipation channel 31 may be formed between each of the first frames 11 and the corresponding light-emitting unit 21.

In some embodiments, a second space may exist between at least two heat dissipation units 22 of a plurality of heat dissipation units 22. The second space may be configured to form a second heat dissipation channel 32.

The second space may refer to a gap between the two heat dissipation units.

The second heat dissipation channel 32 may be a channel different from the first heat dissipation channel 31 and also configured to discharge hot gas. Same as the first heat dissipation channel 31, a form of the second heat dissipation channel 32 may be determined according to a structure and arrangement of the heat dissipation unit 22 and the light-emitting unit 21.

In some embodiments, the second heat dissipation channel 32 may include a second space, or may also include the second space and other spaces. The other space may be a space between two light-emitting units 21, etc.

As shown in FIG. 11 and FIG. 12 , a plurality of the light-emitting units 21 may be provided. The plurality of light-emitting units 21 may be disposed in a one-to-one correspondence with the heat dissipation units 22. The heat dissipation units 22 may be connected with the corresponding light-emitting units 21 to form a plurality of integrated structures. The plurality of integrated structures 20 may be disposed in sequence at an interval, so that the second heat dissipation channel 32 may be formed between two adjacent integrated structures 20, which may penetrate vertically from the light-emitting side to the non-light-emitting side.

When the light-emitting unit 21 is working, airflow below may flow through the second heat dissipation channel 32 to a top of the second heat dissipation channel 32, flow into a central area of the heat dissipation unit 22 from a side of the heat dissipation unit 22, and continue to flow upward, which is beneficial to take away heat in the central area of the heat dissipation unit 22 and can improve the heat dissipation effect. The integrated structure 20 may be found in FIG. 2 .

In some embodiments, an independent heat dissipation unit 22 may be formed by extrusion processing. Different heat dissipation units 22 may be respectively mounted on corresponding light-emitting units 21 to form a plurality of independent integrated structures 20, which is not only beneficial to heat dissipation, but also can prevent other light-emitting units 21 from interfering with adjustment of the light-emitting units 21 of which light-emitting directions need to be adjusted.

In some embodiments, the plurality of integrated structures 20 may be independently disposed, so that a second heat dissipation channel 32 may be formed between two adjacent integrated structures 20. It should be noted that for a plant lamp that does not need to consider adjusting the light-emitting direction of the light-emitting unit 21 by turning, a plurality of light-emitting units 21 may be space apart in the first direction L1, and a heat dissipation unit 22 may be provided with a plurality of light-emitting units 21. A penetrating hole may be then disposed on the heat dissipation unit 22, and a second heat dissipation channel 32 penetrating from the light-emitting side to the non-light-emitting side may be formed by the penetrating hole and a space between the two adjacent light-emitting units 21.

FIG. 19 is a schematic diagram illustrating a structure of a first air channel and a second air channel according to some embodiments of the present disclosure.

In some embodiments, as shown in FIG. 19 , the first heat dissipation channel 31 may include a first air channel 311 and a first air outlet 312. The second heat dissipation channel 32 may include a second air channel 321 and a second air outlet 322. The first air channel 311 and the second air channel 321 may be channels for air flow. The first air outlet 312 and the second air outlet 322 may be through holes for air discharge. In some embodiments, the first air channel 311 may be disposed through the first heat dissipation channel 31. The first air outlet 312 may be disposed on the non-light-emitting side (a side facing the inside of the paper in FIG. 19 ). An end of the first air channel 311 may be provided with a ventilation device (not shown in the figure), such as a fan, etc., configured to blow air to the first air outlet 312. The second air channel 321 may be disposed through the second heat dissipation channel 32. The second air outlet 322 may be disposed on the non-light-emitting side (the side facing the inside of the paper in the figure). An end of the second air channel 321 may be provided with a ventilation device (not shown in the figure) configured to blow air to the second air outlet 322. In a specific embodiment, the ventilation devices may be disposed on the ends of the first air channel 311 and the second air channel 321. Sides of the first air channel 311 and the second air channel 321 toward the light-emitting sides (the side facing the outside of the paper in FIG. 19 ) may be closed. The ventilation devices may supply air into the air channel. The air may be blown out from the air outlet, and at the same time take away heat generated during a working process of a plant lamp. In another specific embodiment, the ventilation devices may be disposed on the sides of the first air channel 311 and the second air channel 321 toward the light-emitting sides (the side facing the outside of the paper in FIG. 19 ). The ventilation devices may be disposed opposite to the air outlets. The ventilation devices may supply air into the air outlets, and at the same time take away heat generated during a working process of a plant lamp. By disposing the ventilation devices and the air outlets, the air flow from the light-emitting side to the non-light-emitting side may be further strengthened, the heat may be taken away, which can enhance the heat dissipation effect.

In some embodiments, by disposing the first heat dissipation channel 31 and the second heat dissipation channel 32, the heat generated during the working process of the light-emitting unit 21 may be simultaneously extracted from the first heat dissipation channel 31 and the second heat dissipation channel 32 in a downward direction to form an upward airflow, which is beneficial to dissipate heat to the light emitting unit 21.

In some embodiments, at least one heat dissipation unit and the light-emitting unit connected thereto may form a non-rigid structure so that space of the second heat dissipation channel may satisfy a preset condition when a position of the light-emitting unit changes.

The non-rigid structure may refer to a structure that can be deformed under an action of external force. The non-rigid structure may be a hinge, a truss, a rotation axis, or the like, or any combination thereof.

The position change of the light-emitting unit 21 may be understood as a change of the position of the light-emitting unit 21 relative to the lamp holder 1, such as deflection and movement of the light-emitting unit 21 and. In some embodiments, when a light-emitting position of the light-emitting unit 21 is adjusted, at least one light-emitting unit 21 may move a certain distance in a certain direction. In some embodiments, when a light-emitting direction of the light-emitting unit 21 is adjusted, at least one light-emitting unit 21 may be deflected by a certain angle in a certain direction.

In some embodiments, when the light-emitting direction of the light-emitting unit 21 is adjusted and at least one light-emitting unit 21 is deflected in the first direction L1, since the light-emitting unit 21 and the at least one heat dissipation unit 22 connected thereto are not rigidly connected, the at least one heat dissipation unit 22 may keep the position unchanged or may only be deflected by a relative small angle in a same direction, so as to ensure that the space of the second heat dissipation channel 32 cannot be affected or basically not affected, so that the space of the second heat dissipation channel 32 may satisfy the preset condition. The space of the second heat dissipation channel 32 may be represented by a width, a volume, etc. of the second heat dissipation channel 32.

The preset condition may refer to a minimum threshold of the space of the second heat dissipation channel that can theoretically achieve a target heat dissipation effect. The minimum threshold may be set by a plurality of manners. For example, the minimum threshold may be manually set, determined by simulation, experiment, etc.

FIG. 20 is a schematic diagram illustrating a non-rigid structure according to some embodiments of the present disclosure.

As shown in FIG. 20 , the non-rigid structure may include a reed 8 and a blocking rod 9. One end of the reed 8 may be connected to the heat dissipation plate 221 of the heat dissipation unit 22. The other end of the reed 8 may be connected to the non-light-emitting side of the light-emitting unit 21. The blocking rod 9 may be fixedly connected to the lamp holder 1 and abut with one side or both sides of the heat dissipation plate 221 (abut with one side shown in FIG. 19 ). A count of reeds 8 and blocking rods 9 may be determined according to a structure and a count of the heat dissipation units 22, which is not limited herein.

Merely by way of example, as shown in FIG. 20 , when the light-emitting unit 21 is deflected from a horizontal counterclockwise to a state shown in the figure, the heat dissipation plate 221 connected to the light-emitting unit 21 should be deflected counterclockwise along with the light-emitting unit 21. But, due to restraint of the blocking rod 9, the heat dissipation plate 221 cannot follow the deflection, and since the reed 8 has a certain elasticity, the restraining effect of the blocking rod 9 only exerts on the heat dissipation plate 221. Therefore, when the light-emitting unit 21 is deflected, the heat dissipation unit connected thereto cannot be deflected, thereby achieving the purpose of ensuring the space of the second heat dissipation channel 32.

In some embodiments, at least one heat dissipation unit 22 may be detachably connected to the corresponding light-emitting unit 21. For example, in an actual application process, a count of working light-emitting units 21 may be chosen according to the light intensity requirements of different regions, different plants or different growth stages of a same plant. When the count of working light-emitting units 21 is reduced, the heat dissipation requirement of the plant lamp may decrease. In this case, a count of working heat dissipation units 22 may be reduced accordingly, that is, part of the heat dissipation units 22 may be selectively detached.

In some embodiments, a whole formed by the plurality of heat dissipation units 22 may be detachably connected to the light-emitting unit 21. For example, due to long-term use of the plant lamp, when the device is covered with dust, and the heat dissipation effect of the heat dissipation unit 22 is poor, the heat dissipation unit 22 may be easily removed and cleaned as a whole to achieve better heat dissipation and prolong a service life of the plant lamp.

FIG. 21 is a schematic diagram illustrating a structure of a heat dissipation unit according to some embodiments of the present disclosure.

As shown in FIG. 21 , in some embodiments, the heat dissipation units 22 may extend different lengths in different directions to form heat dissipation channels with different widths. In some embodiments, the heat dissipation units 22 may formed into a plurality of shapes based on different lengths extending in different directions, which may be rectangular, square or other irregular shapes. In some embodiments, the heat dissipation units 22 may include a plurality of rectangular structures of different widths. For example, when the three light-emitting units of the plant lamp are spaced apart in sequence, the rectangular heat dissipation units 22 and the light-emitting units 21 with different widths may be disposed in a one-to-one correspondence, so that the second heat dissipation channels 32 with different widths may be formed between the heat dissipation units 22 and the first heat dissipation channels 31 with different widths may be formed between the heat dissipation unit 22 and the lamp holder 1.

In some embodiments, the plant lamp may also include an electric control structure. In some embodiments, the electric control structure electrically connected to the light-emitting units 21 may be configured to supply power to the light-emitting units 21 and control the light-emitting units 21 to work. The electric control structure may be in a non-contact manner with the light-emitting units 21. The electrical connection may refer to that the electric control structure is connected with the light-emitting units through a circuit. The non-contact manner may refer to that the electric control structure and the light-emitting units 21 are not in direct contact in the space, so as to prevent a high temperature of the light-emitting units 21 from affecting normal operation of the electric control structure.

In some embodiments, because the electric control structure may also generate heat during a working process, in order to facilitate heat dissipation of the electric control structure and extend a service life of the electric control structure, the electric control structure may be mounted in the lamp holder 1 and located in the first heat dissipation channel 31, and the electric control structure and the light-emitting component 2 may be in non-contact. When the light-emitting unit 21 is working, an upward airflow in the first heat dissipation channel 31 may be used to take away heat generated by the operation of the electric control structure, so as to realize the heat dissipation of the electric control structure. Moreover, the electric control structure may be arranged in a non-contact manner with the light-emitting component 2, which can effectively avoid heating of the electric control structure and ensure heat dissipation effects of the electric control structure.

In some embodiments, the electric control structure may be mounted on an inner side wall of the lamp holder 1, and a third space may exist between the electric control structure and at least one heat dissipation unit 22.

The third space may refer to a gap between the heat dissipation unit and the electric control structure. In some embodiments, the third space may be located within the first heat dissipation channel 31.

In some embodiments, the lamp holder 1 may be provided with connection components 4 on both sides of the second direction. In order to simplify the structure of the lamp holder 1 and facilitate mounting the electric control structure, the electric control structure may be mounted on the inner side wall of the lamp holder 1 in the first direction L1. Specifically, the lamp holder 1 may include four side frames. The four side frames may be connected end to end to form a rectangular frame. The four side frames may be respectively two first frames 11 disposed opposite to each other in the first direction and two second frames 12 disposed opposite to each other in the second direction. The first frames 11 may extend in the second direction. The second frames 12 may extend in the first direction. Two ends of the each first frame 11 in the second direction may be respectively connected to the two second frames 12 to form a rectangular frame. The each second frame 12 may be provided with a mounting seat 42. The first frame 11 may be provided with a mounting groove. The electric control structure may be disposed in the mounting groove and mounted on the first frame 11 by a fastener.

In some embodiments, a count of electric control structures is not limited, which may be one or more. In some embodiments, two electric control structures may be provided, which may be a first electric control structure 51 and a second electric control structure 52. The first electric control structure 51 may be configured to supply power to one of the three light-emitting units 21 and control it to work. The second electric control structure 52 may be configured to supply power to the other two light-emitting units 21 and control them to work. The first electric control structure 51 may be located in one of the first heat dissipation channels 31 and may be mounted on the first frame 11 forming the first heat dissipation channel 31. The second electric control structure 52 may be located in the other first heat dissipation channel 31 and mounted on the first frame 11 forming the first heat dissipation channel 31. It should be noted that arrangement of the electric control structures is not limited to the above arrangement. The count of electric control structures may be determined according to a count of light-emitting units 21 and the structure of the lamp holder 1.

In some embodiments, the two electric control structures may be both elongated structures extending in the second direction. The two electric control structures may be respectively mounted in the inner side walls of the corresponding first frames 11. The first frame 11 may be made of heat dissipation material. In this way, a contact area between the electric control structure and the first frame 11 may be increased, so that part of the heat generated by the electric control structure may be directly exported through the first frame 11 when the heat dissipation of the electric control structure is realized by using the upward airflow in the first heat dissipation channel 31 and heat dissipation effects of the electric control structure can be further improved. For example, the two first frames may be aluminum frames. For example, the two electric controlled structures may be respectively mounted on the corresponding first frames 11.

Furthermore, as shown in FIG. 14 , the two electric control structures may be connected with wires. In order to avoid wiring confusion, the inner side walls of the first frames 11 may be provided with wiring grooves 111 to facilitate placement of wires connecting the two electric control structures. Optionally, two wiring grooves 111 may be provided on the inner side walls of the first frames 11. The wiring grooves 111 may extend in the second direction. The two wiring grooves 111 may be spaced apart in a direction from a light-emitting side to a non-light-emitting side.

In some embodiments, the plant lamp may also include a temperature sensing switch. The electric control structure electrically connected to the temperature sensing switch may be configured to adjust the light-emitting units according to an ambient temperature.

The temperature sensing switch may be configured to detect the ambient temperature. In some embodiments, the temperature sensing switch may be mounted on an outer wall of the plant lamp holder 1 and connected to the electric control structure through a circuit.

For example, when the temperature sensing switch detects that the ambient temperature increases, which may be considered that a light intensity required by the plant is weakened. When a preset temperature threshold is reached, the temperature sensing switch may control at least one light-emitting unit 21 to stop working through the electric control structure, so as to reduce the light intensity of the plant lamp. The preset temperature threshold may be a maximum temperature suitable for plant growth and development set in advance.

In some embodiments, the electric control structure may be electrically connected to the temperature sensing switch and the light-emitting unit 21 may be adjusted according to the ambient temperature, which can not only save energy and electricity, but also ensure the light intensity required for plant growth.

FIG. 22 is a schematic diagram illustrating a structure of a ventilation device according to some embodiments of the present disclosure.

As shown in FIG. 22 , in some embodiments, the plant lamp may also include at least one ventilation device 7. The ventilation device 7 may be a device that can be used to accelerate air flow, such as a draught fan, a fan, etc. which is not limited herein. In some embodiments, the ventilation device 7 may be configured as a fan. The ventilation device 7 may be one or more. A count of the ventilation devices 7 may be determined according to a count of light-emitting units 21. For example, three light-emitting units 21 may be provided. For better heat dissipation, three ventilation devices 7 may also be provided.

In some embodiments, the ventilation device 7 may be mounted in at least one of the heat dissipation unit 22, the first heat dissipation channel 31, the second heat dissipation channel 32, etc. to accelerate heat dissipation. For example, the ventilation device 7 may be mounted on the heat dissipation fin 222 of the heat dissipation unit 22, and the fan may rotate to accelerate air flow near the heat dissipation fin 222 to dissipate heat faster. As another example, the ventilation devices 7 may be mounted on ends of the first heat dissipation channel 31 and the second heat dissipation channel 32. Rotation of fan blades of the ventilation devices 7 may cause air in the first heat dissipation channel 31 and the second heat dissipation channel 32 to flow through an air outlet at an accelerated rate to be discharged to outside, which can further enhance heat dissipation.

In some embodiments, the ventilation devices 7 may be disposed in a one-to-one correspondence with the light-emitting units 21, and may be controlled by the electric control structure. For example, in an actual application process, when a required light intensity decreases due to factors such as a plant growth stage or an ambient temperature, control of the light-emitting units 21 and the ventilation devices 7 may be realized through the electric control structure. Specifically, the plant lamp may be provided with two electric control structures, which may be the first electric control structure 51 and the second electric control structure 52. The first electric control structure 51 may be configured to control at least one of the three light-emitting units 21 and the corresponding at least one of three ventilation devices 7 to work. The second electronic control structure 52 may be configured to work for the remaining light-emitting units 21 and the corresponding remaining ventilation devices 7. When a light intensity required by a plant required decreases, the electric control structure 51 may be configured to stop one or more of the three light-emitting units 21 and the corresponding three ventilation devices 7 from working, so as to satisfy the light intensity required for plant growth and save energy.

In some embodiments, a ventilation power of the ventilation device 7 may be controlled by the electric control structure. The ventilation power may represent power consumption per unit time of the ventilation device 7. It may be understandable that the greater the power consumption per unit time, the greater a corresponding rotation speed of the ventilation device 7, the greater an air supply volume, and the greater the heat dissipation gain.

In some embodiments, the ventilation device 7 may be configured to adjust the ventilation power according to a ventilation power adjustment instruction issued by the electric control structure. In some embodiments, the ventilation power adjustment instruction may be determined based on a machine learning model.

The ventilation power adjustment instruction may refer to an instruction issued by the electric control structure and related to adjusting the power of the ventilation device 7. After receiving the ventilation power adjustment instruction, the ventilation device 7 may adjust the ventilation power to change the ventilation volume per unit time, thereby changing heat dissipation efficiency.

In some embodiments, the electric control structure may adjust at least one ventilation device 7 through different ventilation power adjustment instructions, so as to improve working efficiency of the plant lamp.

In some embodiments, when the ventilation power determined based on the ventilation power adjustment instruction reaches a maximum power value and exceeds a duration threshold, the electric control structure may issue a warning notification. The maximum power value may be a rated power of the ventilation device 7 or a maximum permissible operating power. For example, the maximum power value may be preset by a user or automatically set by the electric control structure according to information of the ventilation device 7.

In some embodiments, the warning notification may include light flashing, beeping, etc., so that the user may intuitively obtain the warning notification of the plant lamp and deal with it in time.

In some embodiments, the electric control structure may determine the ventilation power adjustment instruction based on different light-emitting intensities, different light-emitting duration, and ambient temperatures. In some embodiments, the electric control structure may determine the ventilation power adjustment instruction based on historical data/network platform data/staff experience value, etc. In some embodiments, the electric control structure may determine the ventilation power adjustment instruction based on the machine learning model.

FIG. 23 is a schematic diagram illustrating a determination model according to some embodiments of the present disclosure.

As shown in FIG. 23 , the electric control structure may process a light-emitting intensity 2310, a light-emitting duration 2320, light-emitting direction adjustment data 2350 and an ambient temperature 2360 of the light-emitting unit 21 by using the determination model 2330 to determine a ventilation power adjustment instruction 2370. The determination model 2330 may include a feature extraction layer 2331 and an output layer 2332.

In some embodiments, an input of the feature extraction layer 2331 may include the light-emitting intensity 2310 and the light-emitting duration 2320. An output of the feature extraction layer 2331 may be a cumulative light-emitting feature 2340. An input of the output layer 2332 may include the cumulative light-emitting feature 2340, the light-emitting direction adjustment data 2350, and the ambient temperature 2360.

In some embodiments, the user may also appropriately adjust the relevant data of the ventilation power adjustment instruction output by the model according to the frequency of the light-emitting direction adjustment. For example, when the frequency of light-emitting direction adjustment is greater than a time threshold, the ventilation power may be appropriately increased to prevent a motor from overheating due to frequent work and improve heat dissipation efficiency.

In other embodiments, the light-emitting direction adjustment data 2350 may also include whether the light-emitting direction adjustment instruction is executed in time. It may be understood that when the light-emitting direction adjustment instruction is not executed in time, the motor may be in a fault state. For example, when the light-emitting direction adjustment instruction is not executed in time, the ventilation power may be appropriately increased to prevent the motor from overheating due to failure and causing severe consequences.

In some embodiments, the feature extraction layer 2331 and the output layer 2332 may be obtained through joint training, and the determination model 2330 may be obtained. The output of the feature extraction layer 2331 may be used as part of the input of the output layer 2332.

For example, sample training data, that is, a sample light-emitting intensity and a sample light-emitting duration, may be input to an initial feature extraction layer to obtain a cumulative light-emitting feature output by the initial feature extraction layer. The cumulative light-emitting feature together with a sample ambient temperature and sample light-emitting direction adjustment data may be input into the initial output layer to obtain the ventilation power adjustment instruction output by the initial output layer. An output result of the initial output layer may be verified by using the sample ventilation power adjustment instruction, and verification data of the output result of the initial output layer may be obtained by using a back-propagation feature of a neural network model. The above training may be continued by using the verification data until a trained feature extraction layer and a trained output layer are obtained.

As another example, a sample light-emitting time and the sample light-emitting duration may also be input into the initial feature extraction layer and the output result of the initial feature extraction layer together with the sample light-emitting direction adjustment data and the sample ambient temperature may be input to the initial output layer. A loss function may be constructed based on an output result and labels of the initial output layer. At the same time, parameters of the initial feature extraction layer and the initial output layer may be updated until the initial feature extraction layer and the initial output layer satisfy a preset condition, and the trained feature extraction layer and the trained output layer are obtained. The preset condition may be that the loss function is smaller than a threshold, converges, or a training period reaches a threshold. In some embodiments, a manner for iteratively updating model parameters may include a conventional model training manner such as stochastic gradient descent, etc.

In some embodiments of the present disclosure, the electric control structure may determine the ventilation power adjustment instruction through the determination model, so that real-time adjustment of the ventilation device power may be realized according to an actual situation, which can effectively satisfy requirements of the user, reduce probability of failure of the plant lamp due to poor heat dissipation, and reduce maintenance costs.
